Constructor Detail

SurfParamThread

public SurfParamThread(GISFrame gisFrame,
                       SurfParam sp)

Calculates a given surface parameter.

Parameters:

gisFrame - GIS frame containing raster to process.

sp - Surface parameter to calculate.

Method Detail

doProcessing

public void doProcessing()

Creates a raster containing the surface parameter values. The newly created raster containing the parameter values (e.g. slope map) is added to the GISFrame provided to the constructor as a secondary raster. This can be retrieved directly via this class's method getParamMap(), or by calling gisFrame.getRaster2();.

Note that this method will be called automatically if this is run as a threaded process (e.g. mySurfParamThread.start()). Alternatively it can be called directly as a non-threaded process.

Specified by:

doProcessing in class LSThread

getParamMap

public RasterMap getParamMap()

Retrieves the newly created raster map containing the selected surface parameter values.

Returns:

New surface parameter map, or null if process yet to take place.
